This non-provisional application claims priority to U.S. Provisional Patent Application Ser. No. 62/137,520 filed Mar. 24, 2015 entitled “Door Mounted Computing Device.”

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a security device. More specifically, it relates to a multifunctional portable security surveillance device.

2. Brief Description of the Related Art

In the modern world, security concerns present a serious threat. In the recent years, home surveillance, monitoring, and alarm technologies have become widespread. Most currently available security systems suffer from significant flaws, such as lack of portability, difficult installation and operation, and reliance on extraneous computing devices and monitors.

An example of a home surveillance system is disclosed in U.S. Pat. No. 6,744,463. Surveillance systems of this type utilize a plurality of video cameras each transmitting a video feed to a monitor. Although this type of a security system may be effective for some settings, it has major drawbacks for personal home use. First, the initial setup and installation procedures may be complicated and will likely necessitate services of a trained professional. Second, security systems of this type lack portability. Third, the security system requires a television set or a monitor for viewing the video feed.

Another type of home security system is disclosed in U.S. Pat. No. 8,780,201. This type of security systems eliminates the need for a dedicated monitor by enabling the security device to directly communicate with a smartphone, tablet, laptop, or another computing device through the Internet. This type of security system involves a doorbell-like device that is permanently mounted onto the door, thereby, rendering the device unfit for portable use. For example, an individual concerned with his or her safety while staying at a hotel room will not be able to pack the device disclosed in the '201 patent in the suitcase and quickly deploy the device at the hotel room door. In addition to lack of portability, this device cannot be used in areas where the user does not have an access to the Internet. Furthermore, the device of the type disclosed in the '201 patent cannot be used without a smartphone or a computing device, which significantly undermines its utility for people who do not possess such devices or are not well-versed in computing technology.

Accordingly, there exists an unmet need for a portable security device that can be easily deployed over any door or another object. Furthermore, there exists an unmet need for a standalone security device that does not require any extraneous computing or visual output devices.

SUMMARY OF THE INVENTION

The long-standing but heretofore unfulfilled need for a multifunctional portable security device capable of standalone operation is now met by a novel, useful, and non-obvious invention.

The security device has a strap and two end modules attached thereto. The strap is configured to straddle an object, so that the first end module resides on a first surface of the object, while the second end module resides on the second, opposite surface of the object. The first end module houses a first electronic device, and the second end module houses a second electronic device. In an embodiment, the first electronic device is an input device, and the second electronic device is an output device.

The security device further includes a control unit. A network of electrical connectors is disposed within the strap. The electrical connectors connect the first electronic device and the second electronic device to the control unit. The security device further includes a sensor in electrical communication with the control unit. The sensor is configured to measure a predetermined property. The sensor sends electric signals corresponding to a measurement of the predetermined property to the control unit. The control unit analyzes the input received from the sensor, and responsive to detecting that the signal meets a predetermined criterion, the control unit actuates the first and/or the second electronic devices.

In an embodiment, the first electronic device is an input device, while the second electronic device is an output device. In an embodiment, the first electronic device is a camera, and the second electronic device is a projector. In this embodiment, the camera captures images or video of events occurring on the first side of the object onto which the security device is deployed, and the projector outputs the captured images or video onto the second surface of the object. This feature allows an observer looking at one surface of the object to observe events occurring on the opposite side of the object.

In an embodiment, the sensor is a vibration sensor. The vibration sensor detects vibrations within the object and transmits corresponding electric signals to the control unit. The control unit processes the electric signals and, upon determining that they correspond to a predetermined criterion, actuate the first and/or second electronic devices.

A layer of dry adhesive may be disposed on the strap, the first end module, the second end module, or a combination thereof. The dry adhesive retains the security device in place after its deployed onto the object.

The security device may further contain additional electronic devices disposed within the first end module, the second end module or both. Additional electronic devices are in electrical communication with the control unit. The additional electronic devices are selected from the group consisting of a camera, a motion sensor, a projector, a proximity sensor, a microphone, a speaker, a global positioning system (GPS) receiver, a biohazard detector, an infrared sensor, a temperature sensor, a pressure sensor, a humidity sensor, a gesture recognition device, and a combination thereof.

In an embodiment, the security device has a wireless network adapter configured to connect to a wireless data network. The security device can receive and transmit data via the Internet. In an embodiment, the security device may be wirelessly connected to a computing device, such as a smartphone, thereby enabling the user to remotely control the security device and view data captured therefrom.

In an embodiment, the first end module, the second end module, or both are detachable from the strap, thereby enabling a user to select a module containing an appropriate electronic device/sensor for a user-selectable application.

In an embodiment, the strap of the security device is configured to be deployed over a door. In that embodiment, the thickness of the strap is less than 0.5 inches thereby permitting the strap to reside within a gap between the door and a door frame. The first end module resides on the exterior surface of the door, while the second end module resides on an interior surface of the door. In an embodiment, a camera is housed within the first end module, and a projector is housed within the second end module. Responsive to the sensor transmitting an electric signal to the control unit satisfying a predefined criterion, the control unit actuates the camera. The network of electrical connectors disposed within the strap permits the data captured by the camera to be transmitted to the projector. In an embodiment, the projector outputs images/video onto the inner surface of the door using it as a screen. This feature enables an observer to observe objects, people, and events on the opposite side of the door while the door remains in a closed configuration.

The security device may further include a proximity sensor, a density sensor, or both. The control unit analyzes electric signals received from the proximity sensor and/or the density sensor and determines whether the door is in a first open state or in a second closed state and can determine the exact angle of the door with respect to the frame. The state of the door enables the control unit to analyze with a higher degree of accuracy the signals received from the sensors and actuate an appropriate electronic device to perform a corresponding function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings, which form a part hereof, and within which specific embodiments are shown by way of illustration by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention.

The multifunctional security device 10 is depicted in FIG. 1A. Security device 10 has a first end module 12 and a second end module 14. End modules 12 and 14 are connected to the first and second ends of a flexible strap 16. A layer of dry adhesive 15 may be disposed on strap 16 and/or first and second end modules 12 and 14, thereby enabling security device 10 to be securely attached to and easily detached from virtually any surface.

A network of electrical connectors 18 is disposed within strap 16. In an embodiment, network of electrical connectors 18 is an artificial neuron network, commonly referred to as a neuronet. A first cluster of sensors 20 is housed within the first end module 12. A second cluster of sensors 22 is housed within the second end module 14. The first and second sensor clusters 20 and 22 are in electrical communication with one another via electrical connectors 18.

Sensor clusters 20 and 22 include a plurality of various sensors and electronic components. In an embodiment depicted in FIG. 1B, first and second end modules are detachable from strap 16. This modularity enables the user to select end modules 12 and 14 having sensor clusters 20 and 22 suitable for a particular application. This feature significantly increases versatility of security device 10 by enabling the user to select the data security device 10 captures and outputs by interchanging end modules 12 and 14. Thus, security device 10 may be customized, upgraded, or modified to have different capabilities and perform various functions simply by interchanging end modules 12 and 14.

A control unit 50 resides within security device 10. Control unit 50 receives electric signals from first and second sensor clusters 20 and 22 via electrical connectors 18. Control unit 50 operates under a set of instructions which analyze the input received from sensor clusters 20 and 22. Responsive to the input meeting a predefined condition, control unit 50 actuates predetermined electronic components listed above. For example, responsive to detecting a dangerously high temperature, control unit 50 may actuate speaker 36 to produce an audible alarm.

In an embodiment depicted in FIG. 1B, each end module 12 and 14 has a dedicated control unit 50. This feature allows each control unit 50 to be preprogrammed based on the types of sensors within the sensor cluster of that particular module, therefore, making each module ready for operation without requiring any additional programming or setup. For example, according to this embodiment, the user may purchase a “video and audio surveillance” module, which will be preconfigured with all necessary sensors and control unit 50 operating under a set of instructions appropriate for that specific functionality.

FIG. 2 illustrates some examples of sensors and electronic devices that may be used in first and second sensor clusters 20 and 22. There are two broad categories of these devices: input devices and output devices. Sensors are input devices because they are configured to collect data and transmit that data to control unit 50. Some examples of input devices and sensors are as follows: a camera 24, a vibration sensor 26, a motion sensor 28, a proximity sensor 32, a microphone 34, a global positioning system (GPS) receiver 38, a biohazard detector 40, and other sensors adapted for measuring various environmental conditions including temperature, pressure, and humidity 41, etc. Some examples of output devices are as follows: a projector 30, a speaker 36, a haptic output device 58, etc. In an embodiment, sensors may also reside within the strap 16. For example, strap 16 may contain a load cell, a density sensor, a proximity sensory, etc.

FIG. 2 further depicts a power source 48 supplying an electric current to control unit 50. Although not depicted in FIG. 2, a person of ordinary skill in the art will understand that the power source 48 also supplies electric current to the electronic components of first and second sensor clusters 20 and 22. A person of ordinary skill in the art will further understand that multiple power sources 48 may be used depending on the configuration of security device 10. Power source 48 may be disposed within first end module 12, second end module 14, strap 16, or a combination thereof. In an embodiment, power source 48 may be a battery, a photovoltaic cell, or a fuel cell. In an alternative embodiment, power source 48 may be an electrical power supply, such as an alternating current electrical outlet.

A fundamental principle of operation of security device 10 is schematically illustrated in FIG. 3. In its default configuration, security device 10 is in an idle state to preserve energy, in which most output and input devices within sensor clusters 20 and 22 are powered down. A sensor measuring a particular property transmits an electric signal to control unit 50 in step 60. In step 62, control unit 50 determines whether the input received from the sensor meets a predefined criterion. If the signal does not meet the criterion, it is considered noise and is dismissed in step 64. If an input from the sensor satisfies a predefined criterion, in step 66, control unit 50 identifies electric devices and/or sensors within sensor clusters 20 and 22 corresponding to the input. Control unit 50 actuates the identified electronic devices in step 68. In step 70, control unit 50 processes the data received from the actuated electronic devices and outputs the processed data through one or more output devices.

In an embodiment of security device 10 depicted in FIGS. 4 and 5A-B, security device 10 is configured such that strap 16 straddles a door 52, whereby first end module 12 is disposed on the exterior side 51 of door 52 and second end module 14 is disposed on the interior side 54 of door 52. In this embodiment, camera 24 is housed within first end module 12, and projector 30 is housed within second end module 14. Camera 24 is configured to capture images and/or video of the environment outside door 52, as depicted in FIG. 5A.

In an embodiment, security device 10 includes vibration sensor 26. Vibration sensor 26 monitors door 52 for any vibrations. Upon detecting a vibration, vibration sensor 26 transmits an electric signal to control unit 50. Control unit 50 queries the signal against a database and associates the detected vibration with one or more of the predefined events, such as a knock, a hard knock, a slam, a kick, etc. Responsive to determining the vibration event, control unit 50 activates predefined electrical components.

For example, in FIG. 5B, responsive to detecting a knock, control unit 50 may activate speaker 36 to produce an audible alarm 55—such as a doorbell sound—to alert user 56 that someone is knocking on door 52. Control unit 50 also activates camera 24 facing the exterior of door 52. Control unit 50 further activates video projector 30 on the interior side of door 52. Video projector 30 is configured to project a video feed captured by camera 24 onto the surface of door 52, thereby using it as a screen. This feature makes the door appear semi-transparent, thus enabling user 56 to observe the events, objects, and people on the other side of door 52 without having to open door 52. First and second sensor clusters 20 and 22 may each include microphone 34, speaker 36, camera 24, and projector 30, thereby allowing user 56 to communicate with individuals on the opposite side of closed door 52 whereby each participant can see images/video of one another projected onto the surface of door 52.

This functionality of security device 10 is illustrated in FIG. 6. In step 72, vibration sensor 26 transmits an electric signal to control unit 50 responsive to detecting a vibration of door 52. Control unit 50 compares the electric signal transmitted by vibration sensor 26 against a predefined criterion in step 74. In step 76, control unit 50 determines whether the signal meets the predefined criteria. If it does not, the signal is disregarded as noise in step 78. Responsive to the signal satisfying the predefined criteria, in step 80, control unit 50 actuates camera 24 housed within first end module 12 positioned on the exterior side of door 52. In step 82, control module 50 receives image and/or video data captured by camera 24. In step 84, projector 30 within second end module 14, which is positioned on the interior side of door 52, is actuated. In step 86, projector 30 projects an image/video onto the interior surface of the door using it as a screen, thereby permitting user 56 to observe events occurring on the opposite side of door 52 without having to actually open door 52. This feature of security device 10 enables user 56 to remain within the safety of the dwelling while observing and evaluating the situation occurring outside door 52.

In other embodiments, control unit 50 may be configured to take specific actions based on the input from vibration sensor 26. For example, audible alarm 54 may change depending on whether detected vibration correlates to a knock versus someone tampering with a lock or trying to force their way in. Furthermore, a proximity sensor, a density sensor, or both can be used to determine whether door 52 is in an open or closed state. Different actions are taken by control unit 50 depending on the state of door 52. For example, when door 52 is open, vibrations detected by vibration sensor 26 will vary from vibrations detected when door 52 is closed. State of door 52 is taken into account when querying input from vibration sensor 26 against a database to accurately determine the event correlated to the detected vibration and take an appropriate action.

Although security device 10 disclosed above is a standalone device not requiring any external components or connections, in an alternative embodiment, security device 10 includes a wireless network adapter 53 enabling security device 10 to connect to the Internet. In this embodiment, security device 10 can transmit data to a smartphone or a computer via the Internet to allow users to monitor their dwelling when away from home. Security device 10 can also receive various content from the Internet.

In an embodiment of security device 10, first sensor cluster 20 further contains a gesture recognition camera thereby enabling user 56 to interact with security device 10 via gestures. In an alternative embodiment, user 56 may interact with security device 10 via voice commands. In both of these embodiments, the user can receive visual output projected onto door 52 by projector 30 and provide input in response to the projected content. In addition, gesture recognition cameras and projectors 30 can be housed within both first and second end modules 12 and 14 to enable users on both sides of door 52 to observe images/video of one another and interact with one another. This feature allows security device 10 to transform an ordinary door 52 into an interactive system with an extensive utility for a wide array of applications including entertainment, gaming, video conferencing, educational materials, etc.

In yet another embodiment of the invention depicted in FIG. 7A, security device 10 may be worn by user 56. Due to the structural configuration of security device 10, first sensor cluster 20 will reside on the front of user 56 while second sensor cluster will reside on the back of user 56. This configuration enables security device 10 to simultaneously capture data pertaining to the environment in the front and the back of user 56 as shown in FIGS. 7A-B. FIG. 7B depicts a portable computing device 57 in communication with security device 10. This connection may be accomplished through a wired or wireless connection means known in the art. In this embodiment, user 56 receives information from security device 10 via the screen of portable computing device 57. User 56 can control electronic components and/or sensors in first and second sensor clusters 20 and 22 using portable computing device 57.

In the wearable mode disclosed above, security device 10 has extensive industrial applicability for law enforcement, tourism, data acquisition, and other applications. Security device 10 may further include a haptic output device 58 capable of non-verbally communicating information to user 56. For example, if control unit 50 determines a presence of a threat, haptic output device 58 can alert the user without raising any suspicion. Yet another application of this technology can be for navigation. Haptic output device 58 can direct user 56 to a predefined destination based on signals received from GPS receiver 38 and/or analysis of the surroundings captured by camera 24. Dry adhesive 15 ensures that security device 10 remains attached to user 56 as user 56 moves around.

In the embodiment of security device 10 adapted to be worn by user 56, projector 30 may be used to visually output information to user 56. Projector 30 may be configured to project a map image, a video, or other information onto a surface, such as a palm of hand or the ground in front of user 56. In alternative embodiment, security device 10 may include an integrated monitor screen. The monitor screen may be flexible and may be integrated into strap 16, thereby providing a compact and convenient means for user 56 to readily access information gathered by sensor clusters 20 and 22.
